-LRB- CNN -RRB- -- Tomas Berdych has hovered around the edge of the `` big four '' of men 's tennis for the past three years , but on Sunday he will take center stage in what could be a historic moment for his country .

The women retained their title in the tournament 's 50th staging , and the men are battling to follow up Czechoslovakia 's sole 1980 victory as the 100th edition of the Davis Cup comes to a climax in Prague .

Berdych is ranked sixth in the world in singles play , and 119th in doubles , but he has come to the fore in the Davis Cup this season with 10 wins from 10 matches .

Friday 's victory over Nicolas Almagro , which leveled the final , was his first over a Spanish player after three previous defeats -- including the 2009 final when the Czechs were whitewashed 5-0 in Barcelona .

On Sunday he will play fifth-ranked David Ferrer , who has a leading seven tournament titles this year and 74 match wins -- second only behind world No. 1 Novak Djokovic .
